Matt LaPlantecc2e2762006-10-03 22:22:29 +020075 This is the journalling version of the Second extended file system
Linus Torvalds1da177e2005-04-16 15:20:36 -070076 (often called ext3), the de facto standard Linux file system
77 (method to organize files on a storage device) for hard disks.
78
Matt LaPlantecc2e2762006-10-03 22:22:29 +020079 The journalling code included in this driver means you do not have
Linus Torvalds1da177e2005-04-16 15:20:36 -070080 to run e2fsck (file system checker) on your file systems after a
81 crash. The journal keeps track of any changes that were being made
82 at the time the system crashed, and can ensure that your file system
83 is consistent without the need for a lengthy check.
84
85 Other than adding the journal to the file system, the on-disk format
86 of ext3 is identical to ext2. It is possible to freely switch
87 between using the ext3 driver and the ext2 driver, as long as the
88 file system has been cleanly unmounted, or e2fsck is run on the file
89 system.
90
91 To add a journal on an existing ext2 file system or change the
92 behavior of ext3 file systems, you can use the tune2fs utility ("man
93 tune2fs"). To modify attributes of files and directories on ext3
94 file systems, use chattr ("man chattr"). You need to be using

146 extended fs ext4, based on ext3 filesystem code. It will be

Mingming Caodab291a2006-10-11 01:21:01 -0700149 Unlike the change from ext2 filesystem to ext3 filesystem,

154 a hard limit that ext3 cannot overcome without changing the

849 While we cannot guarantee that it will not damage any data, we have
850 so far not received a single report where the driver would have
851 damaged someones data so we assume it is perfectly safe to use.

875 This is a virtual file system providing information about the status
876 of the system. "Virtual" means that it doesn't take up any space on
877 your hard disk: the files are created on the fly by the kernel when
878 you try to access them. Also, you cannot read the files with older
879 version of the program less: you need to use more or cat.
880
881 It's totally cool; for example, "cat /proc/interrupts" gives
882 information about what the different IRQs are used for at the moment
883 (there is a small number of Interrupt ReQuest lines in your computer
884 that are used by the attached devices to gain the CPU's attention --
885 often a source of trouble if two devices are mistakenly configured
886 to use the same IRQ). The program procinfo to display some
887 information about your system gathered from the /proc file system.
888
889 Before you can use the /proc file system, it has to be mounted,
890 meaning it has to be given a location in the directory hierarchy.
891 That location should be /proc. A command such as "mount -t proc proc
892 /proc" or the equivalent line in /etc/fstab does the job.
893
894 The /proc file system is explained in the file
895 <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
896 ("man 5 proc").

1680 If you want your Linux box to act as an NFS *server*, so that other
1681 computers on your local network which support NFS can access certain
1682 directories on your box transparently, you have two options: you can
1683 use the self-contained user space program nfsd, in which case you
1684 should say N here, or you can say Y and use the kernel based NFS
1685 server. The advantage of the kernel based solution is that it is
1686 faster.
1687
1688 In either case, you will need support software; the respective
1689 locations are given in the file <file:Documentation/Changes> in the
1690 NFS section.
1691
1692 If you say Y here, you will get support for version 2 of the NFS
1693 protocol (NFSv2). If you also want NFSv3, say Y to the next question
1694 as well.
1695
1696 Please read the NFS-HOWTO, available from
1697 <http://www.tldp.org/docs.html#howto>.
1698
1699 To compile the NFS server support as a module, choose M here: the

2035 tristate "NCP file system support (to mount NetWare volumes)"
2036 depends on IPX!=n || INET
2037 help
2038 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
2039 used by Novell NetWare clients to talk to file servers. It is to
2040 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
2041 to mount NetWare file server volumes and to access them just like
2042 any other Unix directory. For details, please read the file
2043 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
2044 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
2045
2046 You do not have to say Y here if you want your Linux box to act as a
2047 file *server* for Novell NetWare clients.

2050 Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

2052 To compile this as a module, choose M here: the module will be called
2053 ncpfs. Say N unless you are connected to a Novell network.

2059 depends on INET
2060 help
2061 Coda is an advanced network file system, similar to NFS in that it
2062 enables you to mount file systems of a remote server and access them
2063 with regular Unix commands as if they were sitting on your hard
2064 disk. Coda has several advantages over NFS: support for
2065 disconnected operation (e.g. for laptops), read/write server
2066 replication, security model for authentication and encryption,
2067 persistent client caches and write back caching.
2068
2069 If you say Y here, your Linux box will be able to act as a Coda
2070 *client*. You will need user level code as well, both for the
2071 client and server. Servers are currently user level, i.e. they need
2072 no kernel support. Please read
2073 <file:Documentation/filesystems/coda.txt> and check out the Coda
2074 home page <http://www.coda.cs.cmu.edu/>.
2075
2076 To compile the coda client support as a module, choose M here: the
2077 module will be called coda.

2081 depends on CODA_FS
2082 help
2083 A new kernel-userspace API had to be introduced for Coda v6.0
2084 to support larger 128-bit file identifiers as needed by the
2085 new realms implementation.
2086
2087 However this new API is not backward compatible with older
2088 clients. If you really need to run the old Coda userspace
2089 cache manager then say Y.
